Enclosed Trailer Questions

I really like that trailer Fly. Thanks for the pics!
Thank you also for the tip on Trailers Midwest - seems like the best prices.

Does anyone know about the Plexcore paneling as opposed to the aluminum exterior?

How about the Dexter axles - spring/torsion??

Learning as much as I can before I get a sales pitch as to why one is better than the other.

Thanks all!

Wally.
